INKSTAN D.

SPECIFICATION forming part of Letters Patent No. 728,545, dated May 19, 1903. Appiiation ined october 21,1902. serai No. 128,182. (No model.) p

To all whom it may concern,.-

Be it knownthat I, CoLoMBAN CoLoMBANI,

a citizen of the Republic of France, residing in Marseilles, France, have invented certain new and usefullmprovernents in Ink-Wells,ot` which the following is a specification.

This invention relates to the general class of ink-wells or ink-pots which may be upset without spilling the ink.

The ink-well which forms the suhjectof this application prevents the ink which it contains from coming out even-if the pot is upset, owing to the arrangement in the neck of the body of the ink-pot of an'obturating-tube,

.which acts as an obturator for the liquid contained in the ink-pot, while at the same time readilypermitting of the introduction of the pen, so as to take the required quantity of ink. This obturating-tube is of india-rubber, and its special feature is its peculiar form, the upper portion being completely hardened and rigid,so as to afford the necessarystrength to resist deterioration by the point of the pen and to maintain this latter in the vertical di rection when it is introduced for taking up ink, while the lower portion, on the other hand, is extremely supple, in order that the two lips which it forms may separate readily, so as to permit of the passage of the pen without effort, these two lips closing quickly and completely upon the Withdrawal of the pen in such a manner as to be well applied one against the other and not to permit o t' the issue of any ink except by means of a pen.

Such is the characteristic feature of the obturating-tube, rendering the ink-pot which forms the subject of this invention unspillable, whilel at thersame time permitting of readily introducing a pen. Its construction may be varied in many ways, more especially as regards the adjustment of the obturatingtube upon the neck of the ink-pot. Various constructional forms of the device are hereinafter described with reference to theaccompanying drawings by way-of example.

Figure 1 is a vertical axial section of the ink-pot. Fig. 2 is anv axial section of the obturator detached, the plane of the section being at right angles to that of Fig. 1. Fig. 3 is a section of the obturator detached, the plane ot' the section being the same as that in Fig. 1. Figs. 4f,v 5, and 6 are views respecslightly-modiiied construction which will be hereinafter described. Figs. 7, 8, and -9 are tively like Figs. 1, 2, and 3, illustrating a l,

ssv

views respectively like Figs. 1, 2, and 3, illustrating a modified construction ofthe obturater adapted for use on an ordinary ink pot or bottle.

In thevarious modifications the obturatingtube consists ot two parts, both of which are ot" indiarubber and intimately connected one with the other in such a man ner that these two lengths of tube in realityV form one piece only. 'lhe upper portion is of india-rubber, hardened to a greater or less extent, while the lower portion, which is constituted by a flattened tube at, forming two lips,which are applied one against the other, is extremely supple and perfectlyy elastic. It therefore readily permits of the introduction between these two lips of` a pen for the purpose of taking ink from the ink'=pot, while the said lips close ,exactly oneagainst thebther iinmediately the pen is withdrawn. This special conformation of the obturator is obtained by pinching together the lower extremity of the tube when it is only half vulcanized. The vulcanization is then completed, and the 0bturator retains its tiattened form with lip's appliedA one against the other, which was originally imparted to it.

As shown in Figs. 1 to 3, the obturatingtube is formed at its upper portion A-that is to say, the portion which is of hardened rubber-with'an internal screw-thread b,

adapted to be screwed kupon the screw-threaded tube c ot' the'cover B of the ink-pot. The body D of the ink-pot and its cover may be arranged in various ways. The arrangement shown in Fig. 1 is perfectly adapted for ll.- ing and cleaning purposes. The tube c of the cover is formed with-,an aperture the diameter of which is just sufiicient to permit of the introduction of a pen into'the obturatingtube, and consequently into the ink-pot. The supple and flattened portion a of the obturator is passed and fixed upon the lower conical extremity of the part` A, and the two india-ru bber parts,the one hard and the other supple, in reality constitute only one piece. The circular projection ol, which is formed upon the periphery of the lower part A, constitutes a pad which serves to insure connec- IOO tion between the two parts A and a of the obtura ting-tube before their intimate connection. In addition to this the obturating-tube is rigidly connected with a washer e, of ilexi- 5 ble india-rubber, which after the obturatingtube has been screwed on comes against the bottom of the cover B. This washer serves to form a joint between the inner end of this cover and the upper edge fof the body of the ink-pot D.

In the modied form of the device illustrated in Figs. 4, 5, and 6 the upper portion A of the obturatingtube is of supple indiarubber, since it isintended to be applied with a certain elasticity upon the olive-shaped tube c. The obturator may also comprise, as before, an india-rubber washer e; but in this case it is preferable to have an independ ent washer, as shown in the drawings in Fig. 4, this washer making, as before, a joint between the lower portion of the cover and the edge of the body of the ink-pot.

Figs. 7 to 9 show the manner in which the novel obturating-tube may be applied to ordinary ink-pots without the aid of an upper cover or cap. The upper portion A of the 0bturating-tube is flexible in its portion c ,which is intended to be turned down around the neck of the ink-pot in order that it may become fixed there by elastic pressure. The rest of the portion A is of hardened rubber and of slightly-conical form internally and externally, so as to present the required pressure upon the neck of the ink-pot. The lower portion a of the obturating-tube of supple india-rubber is formed in the manner described with ref'erence to Figs. l to 3.

Obturating means of any required size or dimensions may be made in accordance with this invention, this being dependent somewhat on the size and shape of the ink-pots to which they are to be applied, and the ink pot or bottle may have a screw cap or cover or not, as hereinbefore explained.

Having thus described my invention, I claim- 1. An obturator for an ink well or pot, comprising a tube to depend into the pot, and a tubular obtnrating part on the inner end of said tube, said obturating part being made from soft, elastic material and flattened laterally at its inner end, whereby the passage through the same is closed.

2. An obturator for an ink well or pot comprising an attaching tubular part provided at its outer end with means for securing it to the ink-pot and at its other end with means for securing it to an obturating portion, and the said obturating portion a., consisting of a soft,

vulcanized-rubber tube which is flattened laterally having its sides brought together and closing the passage through it, substantially as and for the purpose set forth.

3. An obturator for an ink well or pot, comprising an upper tubular part A, provided with a flange e, and an obturating part a, consisting of a tube of soft vulcanized rubber, which is laterally flattened at its free end in a manner to normally close the passage through the tube, substantially as set forth.

4. The combination with an ink-pot and its cover, the latter having a tubular screwthreaded portion c, of an obturator, comprising a flanged tubular part which screws onto the part c of the cover, and an obturating part which is in the form of a tube of soft vulcanized rubber laterally flattened at its free end to an extent suflcient to normally close the passage through the obturator, substantially as set forth.

ln witness whereof l have hereunto signed my name, this 6th day of October, 1902, in the presence of two subscribing witnesses.
